Wanted to give my experience with enabling Pilot Assist 2, at least I believe that's what it is. I have a MY16 XC90 with factory installed Pilot Assist 1 that works up to 30 mph and requires a lead vehicle. I used the config preset option in Orbit to select level 2. The two config items that changed were 023 and 145 (see attached picture). I already had 38 - Top Damping Brakes enabled from factory.
I can now use the PA up to 80 mpg, no lead vehicle required. When it's activated I get a green steering wheel icon below the speedometer, which wasn't there with PA1. I only tried this for about 20 minutes or so yesterday. It worked fairly well for me on highways, except in construction zones where the lines weren't clearly marked. On side streets, even where clearly marked lines, it worked ok but seemed to wonder between lines a little much and I wasn't as confident with it staying in my lane.
